Nokia Corp. continues to lob salvos at Apple Inc. in a patent infringement dispute.
The Finnish phone maker filed a federal lawsuit in Delaware this week claiming that Apple is infringing on seven Nokia patents in products ranging from the iPhone to computers.
The allegations are similar to those in a complaint filed by Nokia this week with the U.S. International Trade Commission. That complaint and lawsuit allege that Apple's iPhone, iPods and computers all violate Nokia's intellectual property rights.
Nokia filed a separate lawsuit in Delaware in October alleging that Apple's iPhone infringes on 10 Nokia patents. Apple denied the claims and countered with its own lawsuit in the Delaware court, saying Nokia has copied aspects of the iPhone in its devices.
